Use four screws and washers when mounting the amplifier to the front rack rails. Rear support is also recommended, especially for mobile or touring use. To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. Requirements NE-series multichannel amplifiers have specific physical, electrical and signal requirements for proper operation. These requirements will vary de pending on your specific application, setup, and the settings on the amplifier. When setting up and testing your system, please take special care to double check all connections and settings. Please refer to the specifications section of this manual for specific input, output and other figures. Constant Voltage Models (25V, 70V, and 100V) and High Pass Filters The 25V, 70V, and 100V amplifiers include internal, factory installed High Pass Filter hardware. This allows for software selectable filters on each channel that prevent low frequency energy from saturating the core of low cost speaker tap transformers. Available settings are 80Hz (12dB/oct), 400Hz (6dB/oct), and OFF. The 400Hz setting is commonly used in paging systems with horn speakers. Note that with the HPF hardware installed, that amplifier can not have any of the optional AES/EBU input, MIC input, or DSP hardware. The DSP option can be factory installed in lieu of the HPF hardware, with HPF frequencies set in software to any value from 20Hz to 20kHz with a slope of 12dB/oct to 48dB/oct and various response options. In order to have AES/ EBU capability in a constant voltage amplifier, the DSP option must be installed. Operating Manual -NE Multi Channel Power Amplifiers 4. REMOTE AMPLIFIER CONTROL ON/OFF/Remote Standby The NE multichannel amplifiers have three possible states, OFF, ON, and STANDBY, each with a status LED on the front panel. Control for these three states is managed by the following: 1) Power Switch -When the power switch is turned off the amplifier is completely off, UNLESS the power switch has been disabled from within Proteane software, in which case the power switch on the amplifier has no effect at all. If the power switch has been disabled from software, the front panel DISABLE LED will be lit. Even if the AC power is removed, the amplifier’s internal memory will maintain the status until changed again from Proteane software. Performing a factory reset will clear and restore all internal amplifier memory to factory settings. 2) Remote Standby Contact Closure -When these two euroblock pins on the back of the amplifier are wired to a switch and connected, the amp will go into Standby mode, whereby the amp is active but not fully powered up. For Remote Standby to work, the power switch must be turned on OR be disabled through Proteane software. 3) Proteane Software On/Standby -On/Standby in the Proteane PE multichannel amp software functions the same as the hardware based Remote Standby Contact Closure on the back panel. Clicking on STANDBY places the amp in standby mode. The On/Standby in software does not override the hardware Remote Standby, they both remian active. 4) Proteane Software Power Switch Enable/Disable -Use this software feature to disallow use of the front panel power switch. If the power switch has been disabled from software, the front panel DISABLE LED will light. The power switch will remain inactive until enabled again from software, even if the amp is removed from power. Preset Recall The four contact closure connections on the back panel euroblock allow for four different amplifier stored presets to be loaded at the instant a remote switch is closed. Presets are configured from Proteane software and can include gain settings, mute status, polarity, as well as the full set of DSP functions if the amp has the DSP option installed. The NE amplifier will store up to 35 named internal presets, each preset storing control data for all channels and audio functions. While working in Proteane software, changes to an individual preset can be saved to the amplifier using , or saved to the PC using . Sub Presets (collections of DSP parameters individually selected from software) are saved in a similar fashion. Individual preset files use the extension (*.pmc). The only way to load presets to an amplifier is by using Proteane software to recall files saved on either the PC or the amplifier itself, through the use of contact closures, or with a WR-5 wall-mounted remote control. Contact closures can load presets 1-4 from the amplifier memory using switches wired to the rear panel contact closure euroblock connector. Caution: A new preset may have dramatically different settings capable of damaging sound system components, so be careful not to recall the wrong preset while the system is on. Data Control The Data Control euroblock connector on the back of the amplifier is used for the Ashly WR-5 programmable zone controller and Ash...
